甲醇柴油双燃料发动机的燃烧特性分析

ANALYSIS OF COMBUSTION CHARACTERISTICS OF METHANOL AND DIESEL DUAL FUEL ENGINE

甲醇在常温下是液态,方便储存和运输,对于船东而言,燃用甲醇燃料的船舶改造费用要远远低于燃用液化天然气和液化石油气,安全性方面,甲醇相对液化天然气和液化石油气要安全得多,甲醇在排放上也优于常规燃料,本文主要从甲醇燃料燃烧特性对甲醇燃料的应用进展进行了介绍。利用chemkin软件对甲醇、柴油双燃料发动机的燃烧情况做了仿真计算。

Methanol is liquid in ambient air conditions which makes it easy to store and transport. When using methanol,the installation costs for the ship-owner is only a fraction of the costs of LNG or LPG. Furthermore,methanol is much more safer than LNG or LPG. Methanol in emissions is cleaner than the traditional fuel oil. This paper mainly introduces methanol from these aspects: Combustion characteristics,emission,layout of the methanol system on ship. Chemkin software is used to simulate the characters of combustion.
